To all 'whom it may concern:

Be it known that l, Vnonev F. Sachin, a citizen of the United States, residing at Kansas City, in the county of Jackson and 5 State of Missouri9 have invented certain new and useful- Improvements in @il Burners; and l do declare the following to be afull, clear7 and exact description ot' the invention, such as will enable others skilled lo in the yart to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the hg ures of reference marked thereon, which form a art of this specification.

"..his invention relates to hydrocarbon oil burners and the primary object of the invention is to provide a novel forni of oil burner so constructed that the oil Will be" vaporized in an eiiicient manner and coin- Zo bine with the requisite amount of air which supplies the oxygen to support combustion.

It is important in, a `device of this lrind that the air passagesa'dmit the air in easy stream lines to reduce friction in the pas- 2@ sage of the air through the air ports and to so arrange the air ports that there Vvvill be no counter or eddy currents Within the burner because if counter' or eddy currents do occur, they produce a roaring noise which obviously is objectionable.

My invention is so designed that the burner will operate Without noise and the air and oil ports are so disposed that the incoming air ard oil vapors Will co-mingle 5 to produce a combustible mixture of maximum eiiciency.

l have also provided an oil burner of ,rugged construction so that it will not easily burn out and the invention contemplates the provision of means whereby liability of carbon accumulation will be reduced to a minimum because as is Well understood, the more perfect the combustion, the less liability of carbon accumulation.

rlhe invention also contemplates a burner construction in which there will bc a minimum number oi parts, each of which is readily accessible for inspection, the parts being simplified s0 that the burner can be easily assembled, and I have also provided means 'whereby the effective port areas may be varied' to regulate the air feed although the latter feature may not, in all cases, be'

necessary.

The novel construction of the invention Fig. 2 is a sectional vievir on the 2 2 of Fig. l. i

Fig. 3 is a mp plan view of the base.

Fig. l is a perspective view of the arch, Eig. 5 is aV perspective view of the base? and Fig. 6 is a bottom plan vicvv of a slightly modilied form of base.

The invention is illustrated as consistin of tvvo main castings, a base l and an arc 2. The base is illustrated as triangular and near the pvolilnt of each angle is an air orifice or port. i e port-s are designated 3, li and 5 and around each port is an upstanding langre 6 toi-support one tubular leg of the arch 2, as rvillloe` explained hereinafter.

The center of the base. is provided with a concavity 7, which constitutes a priming pan for the introduction of oil to be ignited to generate sui'ticieut heat to cause vapori-l zation. A s. ln the center of the base and concentric with the priming pan is an cil inlet orifice 8,lhavin a screw threaded connection by means ot Which a supply pipe 9 may be secured. Surrounding the orifice is a plurality ciA upstanding, ring-shaped ribs l0 of' progressively decreasing heights from the center toward the periphery of the base. The ring-shaped ribs are concentric with the orice 8 and they have inclined sides to provide grooves ll into which the oil may overflov7 from the orifice 8 and since each larger ring is of lessA height than the preceding smaller ring, it is obvious that the oil will flow `from the center vtoward the periphery of the base andinally he received in the @il pan or concave portion 7.

The oil in the grooves as Well as that in the pan can be ignited to supply the initiall heat -Whereby the arch will' be heated to a teinperature suiiiciently high to vaporize the oil and after the initial priming, the arch will be maintained at a temperature sui'iin Acient to cause vaporization of the oil While the burner is operating.

In order that the oil may not oyeriiovr the sides of the base l provide a flow-ofi port l2 in the base, which may be connected to a suitable tank or receptacle adapted to receive the overflowing oil.

Surrounding the rings 10 is a plurality of arcuate lugs 13, 14 and 15, which constitute steps or base supports for corresponding lugs 16, 1'? and 18, carried by the arch 2, the corresponding lugs being designed -to support the central portion oit the arch members 16, 17, and 18 serve a dual function, in that they support the central portion. of the arch and, also constitute` llame dellectors.

The arch has three radial tubular legs 19, 20 and 21, which merge into a central chamber 23 at the center of the arch; the incoming air passing through the legs 19, 2O and 21, however, .being maintained in separate stream lines by the partitions 24, 25 and 26, radially disposed from the center of the archv and connected to the walls of the tubular legs s0 that the incoming air streams through legs 19, 20 and 2l lovv through sep*- aratc chambers until they nally merge into the central chamber 23 immediately above the oil orifice 8.

The legs 19, 2O and 21 of the arch have shoulders 27, 28 and 29, which rest upon the 'upstanding flanges t3 oi' the respective orifices 3, land 5, as will be clearly seen by rei erence to Fig. 2.

Between the tubular legs ot the arch the arch wall is shortened to provide discharge orilices 30, 30 and 3()2 and at the edges of these oriiices are downwardly inclined flanges or lips 31, 32 and 33 to direct the llame downwardly and thereby tend to spread it over a relatively large area. Since there is a flame emitting space between each pair of legs, it will be apparent that the flame Will be emitted from the burner in a broad liet ring. Particularly is this true since the flame emitting spaces are elongated horizontally and since the lugs 16, 17 and 18 support the center of the arch, the spaced relation between the arch and the base will be maintained even though the arch. becomes heated to incandcscence. Ot' course, is desirable to have the arch relatively hot in order that the oil may be thoroughly vaporized and when it mixes with the air, a highly inflammable combustible mixture will be provided.

l prefer to provide 'the orifices 8, fland 5 as Well as the tubular legs more or less oval in cross section and to so upwardly and downwardly curve the legs that the air can enter from the outside to the inside ot' the burner in easily bending stream lines to nib Lacasse commonly present in lmoWn types of burners.

Under certain conditions it may be desirable to control the air intake ports and in order to effect the control l may provide on the base 1 a plurality of radially slidable dempers, shown as plates 311, 85 and 3d, mounted in guides 37MB? 38-38 and 3Q-39 on the base. The damper plates are connected eccentrically to a disk or plate l0 through the medium of the links Ll1, i-.2 and 413, the plates having an odset or lug la to which maybe attached an operating rod d5 accessible from the exterior of the furnace so that the plate can be oscillated about its axis to nieve the plates with respect to the orifices and thereby valve them. The action Will be clearly apparent by reference to Fig. 6.

it will be noted that the partitions 24:, and 26, while vertical, terminate high enough above the oil inlet to provide a relatively large capacity central chamber common to the three chambers formed by the legs 19, 20 and 2l. This is desirable so that the chamber 23 ivill be large enough to accommodate the incoming air from three separate legs and to do this AWithout creating any opposing stream lines or eddy currentti which tend to cause the burner to roar.

When the parts are assembled, oil is admitted through the orifice 8 by opening a valve (not shown) in pipe 9. The feed may be gravity 'led or any other suitable means may be employed. Theinitial oil will flow, over the ringshaped ribs or ballies and it enough oil is introduced, some of it Will flow into the priming pan 7, Where it will accumulate in a pool. This oil is then ignited and as it burns, the arch Will becomeheated. As soon as it becomes hot enough, the oil will begin to vaporize and mixing with the incoming air will provide an eiiicient combustible mixture. Thereafter the burning of the vapors in the burner will be sul'licicnt to maintain the arch hot enough to cause vaporization; it being understood, ot' course, that the arch becomes very hot in practice and as the vapers burn, they Will be directed out in hori Zontal stream lines about the .axis of the burner over a relatively Wide area, the result being a burner of high elliciency which will function With the minimum liability of ditliculty on account ot the accumulation ot carbon and while I do not Wish to be limited -to the particular size or proportions shown, l recommend that the base and arch be rugged enough to withstand liability of cracking due to the intense heat generated and yet light enough so that an unnecessary amount of metal need not be used.
